In the present term 01' construction, as shown in detail in the drawings, the outfit from which one can assemble either a toy locomotive or a toy power plant is shown as consisting of a numdlstinct parts. These parts may be generally described as including the following. A plate A, is, combined controller and brush rigging 1y B, a motor armature unit C, a

, m side plate D, a motor field assembly E, a

mi; oifrednctlon gears F, F, a gear cover plate G, I locomotive trucks H, H having driving wheels and axles, a bottom plate I, provided with contact rollers, a first speed reduction power andassembly J, a second speed reduction assembly K, a power base L, and nine screws.

In making up the toy locomotive, the parts J, K and Lars not employed, while in making up the toy power plant the parts'H and I are not em- The side plate A maybe a fiat smooth steel plate provided with holes, slots and projections such as indicated in the drawings. These special will be enumerated as the description pro- The combined controller and brush rigging assembly B which is shown in detail in Figures 1, 2, 4 and 7 includes a rectangular insulating plate 20 which carries all these parts. This insulating plate carries two connecting straps 21 and 22 the tumor belngthe lead-in connection for the controller as indicated more clearly in Figure 4. The lower end of this strap has an outwardly extending foot 23 for a purpose to be pointed out ghefiipper end of the insulating plate 20 a reversing switch and controller for the motor. reversing switch includes a pivotoperating lever 25 which is mounteddbout a center 26. It carries contacts 27 and flalndicated in dotted lines in Figure 3. These are cooperative with tourposts 29, 30, 3t M11122. The post 29 is connected at the upthe lead-in strap 21 while the post 30 iwooniiected at the upper end 0! the brush lead aim and the post 32 is connected to the other 1 lead strap 33. The post 31 connects with a contact button fixedly carried by the insuiatifis pl te.

a contact straps 22 and 33 each carry a brush as indicated at 35. On making up this brush rigging the lower ends of the straps 22 and 33 are rolled as indicated at 36 to provide a round passageway or holder for a brush 3']. Each of these brushes is carried on the end of a spring 38 which urges it inwardly toward the commutator of the motor. Each of the brush riggings is provided with a. brush lifter in the form of a lever 39 pivoted about the screw 40 and having a free end 41 engageable with the spring 38 to lift the brush.

The insulating plate 20 and the metal plate A are provided with pairs of aligned holes 42 and 43 to receive screws 42' and 43' for fastening these two parts together. To facilitate aligning these two parts, the insulating plate 20 carries pins 44 which pass into holes 44' in the metal plate and the metal plate carries a bushing 45 for the armature shaft, which bushing passes through a hole 45' in the insulating plate. The plate A is also provided with cut-outs as indicated at 46 and 47 which accommodate the prongs 48 used in fastening the conducting strips on the insulating plate 20. The slot or cut out 46 also permits passing the controller handle through the slot as indicated in Figure 2.

The assembly of these two parts is accomplished as indicated in Figure 2 in a very simple manner, it being merely necessary to pass the handle of the controller through the slot, and swinging the parts into position so that the pins 44 pass through the holes 44' and the bushing 45 passes through the hole 45'. The screws 42' and 43' may then be inserted in place and this part of the assembly is completed, as shown in Figures 3 and 4.

The commutator assembly C may, as here shown, include an armature shaft 50, armature field structure 51, armature windings 52, spur driving gear 53 and commutator 54. These parts are provided as an assembled unit and may be inserted into the motor assembly as indicated in Figure 4. To accompany this operation it is merely necessary to press the tips 39 of the brush lifting fingers toward one another and pass the shaft through the bushing 45. This brings the parts to the assembled condition as illustrated in Figure 7.

The plate I) resembled in general the plate A but it is intended for carrying the field structure E. As appears in Figures 1 and 5 the plate D is provided with four small holes 60, and with two short spacers 61 riveted to it and provided with tapped holes 62.

The motor field assembly E is made up to have the usual laminated field structure 63 and field windings 64. This field structure is held together by rivets indicated at 65 and having reduced and portions 66 cooperative with the holes 60 in the frame plate D. The field structure is also provided with screw receiving holes 67 through which screws 68 may be passed to thread them into the tapped holes 62 in the bosses 61 carried by the frame plate. In this manner the field structure and plate may be brought together to place the parts in position as shown in Figure 6.

One end of the field winding is grounded by soldering it to a rivet, as indicated at 64'. The other end 64" is connected to a strap 70 fixedly mounted in the insulating spool ends 64a and 64b. The strap 70 carries a spring pressed plunger 69 which projects outwardly as indicated in Figure 6. It is in a position to come opposite the contact 34 carried on the controller assembly.

The plate D as here shown also carries three spacers or posts '71, "72 and 73 preferably riveted to it and provided with reduced end portions 00- operative with holes "74, '75, and '16 in the plate A. The parts shown in. Figures 6 and 7 may be brought together by merely moving them toward one another in the positions there indicated so as to bring the reduced ends of thesespacers through the corresponding holes after which screws 77 may be passed into the threaded holes '71, '72 and 73 in the spacers to clamp the plates and supporting parts together. When the parts have been assembled to this extent the armature shaft 50 and pinion 53 project out through a'hole 78 in the frame plate D.

The outside of the frame plateD isprovided with two posts 79 shown in Figure 8, adapted to receive the reducing gears F which may be assembled so that the parts will appear as shown in Figure 9. These two gears are each in mesh with the pinion 53. The plate D is also provided with two posts or lugs 80 having reduced end portions and threaded holes. The cover plate (3- above referred to is adapted to fit over the parts asindicated in Figure. 10. Thiscover plate has small holes 81 to'receive the studs 79, has a bearing hole 82 for the armature shaft 50 and is provided with two holes to permit passing screws 83 into the supporting studs 80. All the foregoing parts may be assembled in the manner indicated, and the device in this stage of assembly is in condition for further assembly to, make it into a toy locomotive power plant or a toy unit for general purposes.

Assuming that it is to be assembled into a toy locomotive power plant,1 the operations will be described. During these operationsone employs the two truck units H and thecurrent collector or bottom plate I. As shown in Figure 1 these truck units each have a shaft 89 fixedly carrying a driving gear 90 and a pair of track wheels 91. The shafts 89 also loosely carry bushings 92 h'iLV-w ing undercut portions 93 as indicated." The bushings are held in place by prick marks 89.

The frame plates A and D are providedwith slots 94, 95, 96 and 97. These slots are arranged to be opposite one another in pairs when the frame plates and motor parts are assembled as shown in Figure 10. These slots provide guide ways to receive the bearing members 92, and the next step in assembling the locomotive power plant is to place these two axles and associated parts in position by merely sliding the bushings down the slots thereby bringing the gears 90 into mesh with the reducing gears F. v

The current collector plate or'bottom plate I, as shownin Figures 1, 11, 12 and 13, is adapted to be fastened in place after the running gear has been installed.

This bottom plate and contact carrier consist essentially of a sheet metal stamping 100 which fits the motor frame, and a pair of rail contacting rollers 101 and .102 insulatively supported fromthe stamping 100 and adapted to ride on the third rail of thetoy railroad track on which the locomotive is to be used. To insulatively support the rollers a strip of insulating material 103 is secured to the stamping 100. As here shown the method of securing these parts together includes aplurality of prongs 104 bent over onto the strip of insulation and a pair of apertured prongs 105 adapted to receive the reduced end portions .106 of the insulating strip. This insulating strip carries a flexible metal strip 107 on the ends of which are mounted saddle pieces 108 which extend down through holes 109 in the motor frame.

stampinglOO so as to carry the rollers 101 and 102 spaced below the body of the stamping 100.

The resilient roller supporting strip 107 is held in place on the insulating strip 103 by a stamping 118 and prongs 111, which are folded over the metal strip 107 and underneath the insulating strip 103,.the stamping 100 being cut away as indicated at 112 in section in Figure 13 to keep the prongs 111 out of contact with the stamping. The contact carrier 16? is prevented from twisting out of place by the roller supporting saddles 108 which pass down alongside the fixedly carried insulating strip 103. The stamping carries a spring pressed plunger 113 for a pur pose to be described.

The stamping 100 is shaped so as'to securely fit the motor parts heretofore assembled and is arranged that it cannot be improperly placed in position on the same. The stamping has upwardly bent end members 114 and 115 slotted as indicated at 116 and adapted to pass outside the posts '71 and '72. The sides of the stamping 100 are provided with four upwardly extending projections 11'? adapted to fit outside the frame plates A and B and to engage with the bushings 92 on the shafts of the running gear. The plate A is provided with projections 118 adapted to pass through slots 119 in the stamping 100 thereby preventing assembling these parts improperly.

To complete the assembly of the locomotive motor the bottom plate 100 and parts carried thereby is inserted in place, which may be accomplished by merely lowering it from the position shown in Figure 11. onto the structure as indicated inFigure 10. This permitsthe slots 116 to by the shanks of thumb screws 12%) carried the spacers "i1 and 72'. Atthe same time the projections 117 are brought against the bushings on the wheel axle shafts and when the thumb screws are tightened this bottom stamping and contact carrier is secured in position.

During this operation the spring pressed plunger 113 is brought against the outstanding foot 23 on the controller brush rigging unit B. The relative position of these parts at that time are indicated in Figure 1. When the parts have been assembled as has been described, the complete power plant for the toy locomotive will have been assembled utilizing the parts designated as A, B, C, D, E, F, G, H, I and the nine screws provided in the outfit. It will be noted that it is unnecessary to connect or disconnect any wires whatever in assembling the motor. All electrical parts are securely carried by various subassemblies and when they are put together, all necessary connections are made.

. The path of current through the motor may be described as follows: From the contact rollers 101 and 102Ythrough the yielding spring supporting strap 107. to the stamping 110, thence through the spring pressed plunger 113 to the foot 23 of the strap 21, then tm ough the reversing switch or controller and brush rigging and through the motor armature where the current is carried to the contact button 34 on the controller unit. This current will continue through the field winding to the field structure and thence to the The extent of movement of the running switch 25 is limited by two stops 113 on the plate A. v

In order to facilitate assembly of the motor, the two screws 12' and i3, used for fastening the controller brush assembly onto the plate A, the three screws 77, used for fastening the plate A onto the spacers ll, 72 and 73, and the two iii acrews 83, used for fastening the plate G in position, are all the same size and length. The two screws 68, used for fastening the field assembly onto the plate D, are longer but may be made to have the same thread.

When it is desired to assemble the outfit into the form of a toy electric power plant for operating various forms of toys, the parts are as above described assembled to bring them to the state or condition shown in Figure 10. Instead of using the units H and I to make up a toy locomotive one uses the units J, K and L to make up a toy power plant.

The unit J has a shaft 130 similar to the shaft 89, and is provided with a gear 131 like the gear and with bushings 132 like the bushings 92. The shaft Jalso carries at one end a comparatively large pulley 133 and at the other end a small pulley 134 and a pinion 135.

The unit K has a shaft 136 which carries a large gear 137, a drum 138 and a sprocket wheel 139. In assembling these parts the unit K is first inserted in place by passing the shaft portion 136 thrbugh the holes 140 and 141 in the plates A and D. make improper assembly impossible, these hoies are larger than other holes in the side plates, and may be the only holes opposite one another. The unit J is lowered along the slots in the same manner that the units H were inserted bringing the gear 131 in mesh with the reduction gear unit F and bring the pinion 135 into mesh with the gear 137 on the unit K. As this gear 137 comes in behind the pulley 134 the unit K is securely held in position so that it cannot slide out of its bearings.

The base plate unit L is then inserted in place. This unit as shown in Figures 1 and 15 is in the form an inverted channel shaped stamping 150 support the power-plant on a fiat surface. Thisstamping 150 has upwardly bent side lugs 151 corresponding with the lugs 117 carried by the unit I and adapted to pass outside the frame plates A and D as indicated in Figure 15. One pair of these lugs will secure the unit K in position, the other pair merely passing up outside the motor frame to facilitate aligning the motor The stamping 150 is also provided with two lugs 152.similar to the upwardly bent ends 114 and 115 so that the unit L may be fastened onto the spacers 71 and 72 by the thumb screws 120 as indicated in Figure 15. The stamping 150 also carries an upwardly and inwardly extending shell 163 adapted to pass inwardly between the lugs 118 on the plate A. The end 154 of the stamping carries a pair of binding posts 155 and 156 one of which is insulatively supported from the face plate. This insulated binding post 156 is connected by means of a conducting strip 157 with a plunger member 158 similar to the plunger member 113. The plunger member 158 is carried by "the shelf 153 and the contact strip 157 is covered over and supported by i an insulating strip 159.

When the units J, K and L are assembled as have been described, the electrical connections for the motor have been simultaneously completed. The current can pass from the binding post 156 through the strap 157 and plunger 158 to the foot 23 carried by the controller unit B and thence through the motor which has been described.

When the unit has been assembled for power plant purposes it will be apparent that one has available a high speed pulley 132, a low speed pulley 134, and a still lower speed winding drum 138 and sprocket wheel 139.

It is obvious that the invention may be embodied in many forms and constructions, and we wish it to be understood that the particular form shown is but one of the many forms. Various modifications and changes being possible, we do not limit ourselves in arnr way with respect thereto.
